Before the introduction of the laser, many birthmark problems we are helpless, some traditional treatment including peeling, abrasion method, etc. will not be effective and easy to cause the formation of scars, not only no cosmetic effect, but also cause unnecessary “disfigurement”.
Expert Review]
The birth of the laser has brought a revolutionary victory in beauty, how does the laser treatment not leave scars?
1, “selective photothermal action principle”.
When the laser irradiates the skin to be treated, it will be absorbed by the pigment in the treatment area, and the laser instantly explodes with huge energy to act on the pigment mass, abnormal capillaries and other skin lesions, so that the pigment is broken up, decomposed, engulfed by phagocytes and discharged with the lymphatic circulation to remove pigmentation, abnormal capillaries and other skin problems, without harming the normal parts of the skin.
In addition, some pigments are brought out through crusting off, which can be understood as follows: for example, in the treatment of nevus of Ota, the traditional treatment method is to take a “simple and brutal” approach, directly “cutting off” the abnormal skin, while laser is a “high-tech but gentle” method. The laser is a “high-tech but gentle and elegant method” that allows these pigments to become smaller and then slowly excreted from the body.
2. Interesting simulation experiments.
Many laser beauty treatment experts have done such a simulated experiment: a black balloon was put inside a white balloon, when fired with our machine on the balloon, the black balloon inside burst instantly, while the white balloon outside remained intact, that’s how amazing! The black balloon is like our pigmentation, and the white balloon is like our normal skin. The laser only works on the pigment that needs to be treated, without damaging or only slightly damaging our normal skin.
Another example is the light shining through the glass into the house, the glass doesn’t have any damage, just like when the laser works on the skin lesions, it doesn’t harm the normal skin.
But for the laser to act precisely on the lesion without damaging our normal skin and leaving scars, these points are very important: the selection of the appropriate laser wavelength, pulse width, and energy, and the control of the treatment response, all of which require the treating doctor’s full knowledge of skin and laser fundamentals, familiarity with laser equipment, and extensive clinical experience. Of course, it also needs to be combined with proper post-operative care.
3, that laser beauty is not absolutely safe without side effects:.
Laser cosmetic surgery is also relatively safe, if the performance of the equipment is not good, the patient’s own basal skin is not good or the operator’s clinical experience is not enough, there is also a certain risk.
Here is an example: the treatment of nevus of Ota!
1.What is nevus of Ota? Nevus of Ota is a blue-black flaky patch that occurs on the face, especially around the eyes, mostly unilaterally, but a few are bilaterally symmetrical. Although it is a kind of birthmark, it doesn’t mean that it must be there when the child is born, and some of them will appear several months to years after birth, or even decades later.
2.Why won’t it leave scars? The new laser has automatic identification function, which can identify the lesion tissue to be destroyed precisely like a missile during the treatment process, and at the same time can reach the lesion directly without damaging the normal skin tissue, so that the pigment particles in the lesion are broken and destroyed under the powerful laser irradiation, and become very small pigment particles, so small that they can be swallowed and discharged by the phagocytosis system in the body. Since the laser does not damage normal tissues during the treatment, the whole treatment is very safe and will not leave scars.
3.The efficacy and period of laser treatment for nevus of Ota
The efficacy of laser treatment is related to three factors: the laser equipment, the treating physician and your own response to laser treatment. Since the pigments in the lesion are distributed in heaps in three dimensions in the skin, each treatment can only destroy some pigments, and it takes 3-6 months for the broken pigments to be discharged through phagocytosis in the body, so all treatments for nevus of Ota are generally once every 3-6 months, and multiple treatments are needed.
Many patients and their families would like to know how many treatments are needed? The number of treatments required for each individual varies greatly, and no doctor can give you an exact answer. Because even if you are treated by the same doctor with the same machine, the response of each person to laser treatment is very different, plus the fact that the condition of each patient varies from light to heavy, the pigmentation varies from deep to light, and the metabolism and self-recovery ability varies from strong to weak, the number of treatments varies greatly from person to person.
The effect of nevus of Ota treatment is very good, but you must have patience, because after each treatment, the pigment particles that have been broken down need to be metabolized and swallowed by the body, so the effect is not particularly obvious immediately after treatment, but slowly fades within 3-6 months.
【Opinion】.
Laser treatment is highly selective and precise, like a “missile” that can reach the lesion without harming the normal skin, so it can achieve the magic of not leaving scars. However, some “laser grinding” treatments, such as pigmented moles, have the risk of scar formation.
